Abstract
Abstract This invention is a releasable pulley device that can be readily attached to the center rear of a boat trailer and through which the tow-in line for a boat is threaded. As the boat is winched in to the rear of the trailer an alignment of the prow with the center rear of the trailer is effected. The pulley device is released from its seating and rides free on the line as the boat is fully winched on to the trailer. This enables the dry loading of a boat from rough water as a one-man operation.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
189 words
In combination with a boat trailer adapted to be towed and having an elongated bed provided with support means for cradling a boat in centered position loaded on the trailer, and further provided with a loading winch stationed at its forward end including a loading line extendable therefrom to be fastened to the bow of the boat for loading the same from the water onto the trailer, guide means in running engagement with the loading line by which to draw the bow of the boat to the after end of the trailer in transversely centered loading position, said guide means comprising a captive line guide through which the line is free to run and that remains captive on the line, and line guide mounting means fixed in transversely centered position on the trailer bed adjacent the after end thereof, said line guide being engageable with the mounting means for locating the line guide substantially at the level of the bed while drawing the boat into loading position, and being selectively releasable from such mounting means thereafter to permit loading of the boat onto the trailer from such loading position.
Claim 2
Dependent Claim
189 words
In combination with a boat trailer adapted to be towed and having an elongated bed provided with support means for cradling a boat in centered position loaded on the trailer, and further provided with a loading winch stationed at its forward end including a loading line extendable therefrom to be fastened to the bow of the boat for loading the same from the water onto the trailer, guide means in running engagement with the loading line by which to draw the bow of the boat to the after end of the trailer in transversely centered loading position, said guide means comprising a captive line guide through which the line is free to run and that remains captive on the line, and line guide mounting means fixed in transversely centered position on the trailer bed adjacent the after end thereof, said line guide being engageable with the mounting means for locating the line guide substantially at the level of the bed while drawing the boat into loading position, and being selectively releasable from such mounting means thereafter to permit loading of the boat onto the trailer from such loading position.
Claim 3
Dependent Claim
75 words
The combination defined in claim 1, wherein the line guide comprises a pulley rotatively mounted on one end of a support shaft, and wherein the mounting means comprises a block having a receptacle hole therein slidably receiving the shaft, and manually releasable detent means in the block holding the shaft in said receptacle hole, including a pull line extendable to the forward end of the trailer for releasing the detent by pulling on such line.
Claim 4
Dependent Claim
22 words
The combination defined in claim 2, wherein the block has two similar receptacle holes oriented substantially at right angles to each other.
Claim 5
Dependent Claim
64 words
The combination defined in claim 1, wherein the line guide is engageable and disengageable in relation to the mounting means in a direction transverse to the loading line when the latter is stretched under tension between the winch and the boat during loading, whereby line tension exerts disengagement force on the line guide to withdraw the same from the mounting means when released therefrom.
Claim 6
Dependent Claim
75 words
The combination defined in claim 4, wherein the line guide comprises a pulley rotatively mounted on one end of a support shaft, and wherein the mounting means comprises a block having a receptacle hole therein slidably receiving the shaft, and manually releasable detent means in the block holding the shaft in said receptacle hole, including a pull line extendable to the forward end of the trailer for releasing the detent by pulling on such line.
